SD-Anti-DDoS: Fast and efficient DDoS defense in software-defined networks

In order to overcome Distributed Denial of Service (DDoS) in Software Defined Networking (SDN), this paper proposes a mechanism consisting of four modules, namely attack detection trigger, attack detection, attack traceback and attack mitigation. The trigger of attack detection mechanism is introduced for the first time to respond more quickly against DDoS attack and reduce the workload of controllers and switches. In the meantime, the DDoS...
